STAPLE-BINDING DELIVERY MECHANISM FOR PRlNTlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 510,845, dated December12, 1893. Application filed August 19, 1893. Serial NO. 433570. (Nomodel.)

To all whom it mag concern.-

Be it known that I, LUTHER O. CROWELL, a citizen of the United States,residing at Brooklyn, county of Kings, and State of New York,

have invented certain new and useful Improvements in StapleBindingDelivery Mechanism for Printing-Machines, fully described andrepresented in the following specification and the accompanyingdrawings, forming a to part of the same.

This invention relates to that class of stapling devices more.particularly adapted for attaching together or binding the plies ofmoving material such as the product delivered from a printing mechanism;and more particularly to that class of stapling mechanisms which are ofthe rotative type or such as have staple inserting means that moverotatively to co-operate with a clinching device in the operation ofinserting the staple and clinching its legs, whereby the rapid onwardmovement of the material to be stapled may be maintained and a rapidproduction of the finished product take place, as is more particularlyset forth in my application, Serial No. 464,007, filed February 28,1893.

The invention as embodied herein consists of a rotative mechanism inwhich the staple holder or presenting tool is made to oscillate and thusmoveto and from the staple setting point, and the invention embraces thenovel constructions hereinafter fully described, shown and claimed.

The drawings illustrate a practical struct- 3 5 ural embodiment of theinvention, in which- Figure 1 isaside elevation of so much of a deliveryapparatus of a printing machine as is necessary to illustrate thecombination therewith of this improved stapling mechan- 4o ism. Fig.2 isa side elevation of the stapling mechanism opposite to that shown inFig. 1. Fig. 3 is a plan view thereof, showing more particularly thewire feeding mechanism. Fig. 4 is a longitudinal sectional elevation 5through the upper member of the compound tool, on the line a of Fig. 6,and shows the staple bender in plan and partly in section. Fig. 5 isa-similar view on the line 5 of Fig. 6, and shows the staple driver inplan. Fig.

of the compound tool when the same is in the raised position shown inFig. 1. Fig. 7 is a front end elevation ofthe staple holder orpresenting tool. Fig. 8 is a plan view of the wire cutter. Fig. 9 is aperspective view of one of the cams. Figs.10 and 11 are front and sideelevations of the staple clinching device.

Although no machine for the production of the material to be stapled isshown herein, it is to be understood that the rollers 75, 76 illustratea pair of rollers through which plicated sheets or webs are carriedoutward for delivery, as from a printing machine. The plicated sheetsmay be led for final disposition, into a folding machine, whereby theywill be doubled one or more times and laid fiat in a pile. WVhen,however, the product passing the rollers is in the web form the plicatedweb or webs will be severed transversely by a cutting mechanism and theresulting sheets be finally delivered as by folding. In this improvedmeans for delivering such products the same are to be united to getherin, onor along their ultimate binding line by small wire staples passedthrough the plies and clinched in place, the stapling apparatus forapplying these staples being preferably located between said deliveryrollers 75, 76 and the final delivery apparatus, as the cylinders A, B,which latter may be supplied with cutting and folding mechanisms, one orboth, as is common in the printing art and as is fully set forth in mysaid application, Serial No. 464,007.

As the preferable object of the stapling mechanism is to unite togetherplicated material received from a printing machine it will be understoodthat the printing machine may be of any construction that will producesheets or webs plicated as they emerge from Thus two or more printingmachines provided with means for associating sheets or webs will producea compound product as one consisting of two or more sheets or webs,while a printing machine having two or more sets of complete printingmechanisms operating upon a single width of web or sheet and providedwith a slitter or slitters and a longitudinal folder or folders,

will produce a plicated product; hence, it will be understood that thisstapling mechanism is adapted as a part of the delivery appara tus ofany printing mechanism that delivers sheets or webs plicated byassociating rollers, bars or folders, and whether or not, when webs areprinted upon, the same are severed into sheets before or after the samereaches the delivery rollers 75, 76.

In the structure of stapling apparatus shown, the parts are arranged toset the staples at right angles to the travel of the material to bestapled. I11 this arrangement there must of course be as many of thesestapling apparatuses as it is desired there shall be staples in thematerial. Ordinarily two staples will be sufficient, but three or moremaybe setlin an aligned row widthwise of the material or transversely toits run through the apparatus, but it may be here remarked, that byslight modification, mechanisms may be arranged so that the staplesWilli) be set in the direction of the run of the we In this staplingapparatus, as illustrated, the staple is formed, carried to andpresented at the staple setting point, by a staple inserting means, theholder or presenting tool of which oscillates from the point ofreception of the staple to the setting point thereof, where it isinserted and clinched in the material by means of a driver or insertingtool, in this instance reciprocating in said holder or presenting tool,and a stationary co-operating clinching die. The oscillation of theholder or presenting tool is preferably so timed that as it approaches,reaches and passes the staple setting point, its direction of and speedof travel is that of the moving material through which the staple is tobe inserted, and in which it is to be clinched or set. In the returnmovement of its oscillation this holder or presenting tool returns tothe wire feeding mechanism, cuts off a staple length of wire, and saidwire length is formed into a staple and delivered Within the presentingtool or holder, ready for a repetition of the downward movement orcarrying or presenting operation.

The wire feeding, staple forming, holding, presenting or carrying andinserting tools or devices are all supported upon a stationary platebracket 100 which projects from an arm 101 that is secured to the frameof the ma chine and is suitably located beneath the delivery rolls 75,76 through which the plicated material to be stapled is fed onward fordelivery.

The movements of the stapling mechaih isms are imparted by a connectingrod 51, that is reciprocated by timely movements imparted by a cam 52which is for convenience shown as fixed upon theshaft of the cylinder A,which is one of a pair A, B that supports cutting mechanisms, by whichthe stapled material is severed into sheet lengths, and which may alsocarry folding devices for folding the staple sheet if desired. This cam52 is suitably shaped to give the requisite movement to the stapleholder or presenting tool and the staple driver inserting tool or devicereciprocating therein, so that the speed of movement of the holder orpresenting tool at the time of the setting of the staple shall c oincidewith the movement of the material in which the staple is to be set.

The stationary plate bracket 100 1s provided with a wire feeding slot 9through which the wire 4 is fed by means of a reciprocating clampingslide 20, that is guided in an arm 21. The wire received from a wheel ispassed through said slot and nipped in the feed ng direction by a pawl22 carried by the slide and held against any return movement by a pairof spring seated dogs 23, 2 1, the necessary reciprocatory motion beinggiven to the slide 20 by means of a bell-crank 25, and a reciprocatingrod 26, abowl attached to wh ch runs in the slot of a vibrating cam 27,which cam swings on the shaft 28 over which shaft the rod 26 slides bymeans of its bifurcated end.

The holder or presenting tool and the forming tools have their center ofmotion upon the shaft 28 so as to have a rotative movement, namely, anoscillation. The carrier, 29, which contains the forming anvil 31 andprovides cooperating bending arms 2, 3, is SIIOWH'IIJ section in Figs.3,4,5 and 6, and ahead which is provided with a wire slot 10 for therecep tion of the staple length of wire that is fed to it through thedirecting slot 9 in the plate feed 100. This carrier 29 has a downwardmovement determined by i a rest block 30 which supports said head withits wire slot 10 aligned with the slot 9, so that the staple length ofwire may be fed into said head to a distance suitable for the formationof a staple, and said carrier 29 is capable of rising above said block30 a suitable distance in aid of the operation of forming the staple.The head of this carrier 29 is made hollow to a size adapted to receive,support and guide a reciprocating forming anvil 31, that carries a rack32 through which it is moved to and fro by means of a rocking segment 33carried by a lever 34 that is hung in bearing arms 5, 6 fast to theanvil 31, the slotted upper end of which lever 34 is controlled by apivot 35 fixed to the plate 100.

The staple holder or presenting tool is shown in Figs. 3, 5 and 6 insection. It is hung to oscillate upon the shaft 28 and has the cam 27attached to it. This presenting tool 39 is capable of moving downward toor slightly beyond the dotted position of it shown in Fig. 1, and upwardto a position slightly above that shown in full lines in the samefigure. This presenting tool 39 is recessed longitudinally to form twoholding arms 7, 8, the inner sides of which are provided withlongitudinal slots approximately of the size of the wire from which thestaple is formed, into which the staple legsare carried or drawn duringthe formation of the staple, as will presently be explained. This holderor presenting tool 39 is also provided in its inner sides withlongitudinal guide slots in which reciprocates the driver or insertingtool 41. This driver 41 is provided between the base of the presentingtool 39 and its own rear end with a spring42 preferably supported on arod, as shown, and on one side there projects from the driver 41 a stud43 that engages a fixed cam plate 44 as the stapling inserting meansmoves upward, and a trigger cam 45 as the said staple inserting meansmoves downward. This trigger cam'45 is pivoted so as to slightlyswing,it being'held in its forward position against a stop 47 by meansof an arm 46 attached to its shaft and borne upon by a spring 48. Theoscillating movements are imparted by means of the cam 52 through theconnecting rod 51, which vibrates a two armed swinging lever, to one arm53 of which the connecting rod is attached, and the other arm 54 ofwhich is connected by a link 55 with a rock arm 56 attached to the rearend of the staple holder or presenting tool. When the said holder orpresenting tool 39 which carries or transports the staple from theforming point presents it to the inserting point of the material andmoves with it down to the setting point, afterward makes its upward orreturn movement, it will not only come in contact with the carrier 29,but lift the same from ofi the rest block to a distance sufiicient toenable the cutter 36, which is fixed to the holder or presenting tool tosever a staple length of wire by the movement of said cutter past thewire feeding slot 9, and immediately following the cutting of the wireas the upward concerted movement of the carrier 29, and the holder orpresenting tool 39 is continued, the slotted arm 34 will move over the'pin or stud which will act to rock the segment 33 rearward, and throughthe rack 32 impart a like movement to the forming anvil 31 which will insuch rearward movement draw the wire length inward thus causing thebending arms 2, 3 to bend the ends of the wire length at right angles toits central body portion, thereby converting the same into a staple, thelegs of which are drawn within the grooves in the inner faces of thearms of the holder or presenting tool 39 while the crown or head of thestaple rests against the end of the driver or inserting tool 41, as seenin Figs. 5 and 6, which driver 41 is then held in its rearward positionby means of its arm 42 bearing in senting tool 39, and, as that memberfurther descends, the staple will be transported or carried by it intoposition relative to the material foritsinsertiontherein. Now while thisholder or presenting tool 39 is makingits downward movement its stud 43will pass onto the rear face of the trigger cam 45, the curvature ofwhich will slightly but still further compress the spring 42, and, whenthe forward end of the holder or presenting tool 39 has reached thesetting point for the staple, the'stud 43 of the setting tool the arm 43of the driver will pass off from the lower end of the trigger cam 45,thus releasing the spring 42, which will suddenly and with great powerquickly expand to thrust said driver or inserting tool forward until itis arrested by the rear ends of the arms 7, 8, thus carrying before itthe staple, causing the same to be entered through the material and thelegs thereof to be clinched by a suitable clinching device as a fixedblock 37 having a shallow recess or die with curved ends therein. Thisinserting and clinching operation will, therefore, be performed whilethe staple holder orpresenting tool is moving in the same direction andwith substantially the same surface speed at which the material istraveling, and hence be performed without injury to the moving material,and as soon as the staple is inserted and hasits legs clinched down, itwill be relieved from any hold by the presenting and inserting tools .sothat the same may be retracted or moved upwardly while the materialcarrying the staple moves onward. During this downward movement of theholder or presenting tool 39, and it may be during its partial return, awire length is again fed forward into the head of the carrier 29, andwhen the holder or presenting tool 39 moves upward, its stud 43 willpass in front of the trigger cam and making contact with the cam plate44 will be gradually moved rearward, thereby compressing the spring 42,and when the holder or presenting tool 39 comes in contact with thecarrier 29 it lifts the same, causes the cutter 36 to severawire length,the segment 33 torock and draw the forming anvil rearward, thus bendingsuch wire length into staple form, and depositing the same in thegrooves in the arms of the holder or presenting tool 39 with its crownor head resting in front of the driver or inserting tool 41.

The staple inserting means consist generally of astaple holder orpresenting tool which holds or presents the made staple so that its legsshall properly enter the material, and a tool or driver which acts tocompel theentrance of the staple into the material. The holder orpresenting tool may also act as a tool or driver for inserting thestaple into the material, but it is preferable in this form of themechanism that a separate and movable tool or driver shall be present.

The clinching mechanism may be of any suitable form but as herein shown,and asjs preferred, since the operation of the setting mechanism is avery rapid one, said setting tool may be a simple block or clinching die37, as shown in Figs. 1, 10 and 11, the face of which is provided with atransverse recess, the ends of which are slightly curved to cause thestaple legs to bend inward. or toward each.

other, and which recess is continued downward in the block so that theclinched staple legs may pass out of or oil from the same Withoutobstruction, and it is preferable to continue the curvature orinclination of the ends of this recess throughout the depth of theblock, so that the actual clinching may be prolonged slightly to insurea perfect operation.

The cylinders A, B, are shown by peripheral lines only, since they maybe provided with simply cutting mechanisms, or cutting and foldingmechanisms, asis fully described in my said application, Serial No.464,007, and in my applications, Serial Nos. 483,191 and 483,192, filedAugust 15, 1893.
